I have a hub based on an old Philips chip (now NXP). I found a datasheet online that, if I'm correct, has given me the pin that controls the power to the downstream ports. Before I get too in to it, I'll wait to see if I can come up with something with more ports on Friday. I'm a bit leery of going for one of the super cheap hubs as I might end up with a power supply that has...well, lofty aspirations. And while I won't need 3.5A (500mA x 7 ports) I might need about 2 or 2.5A continuously. Thanks!
